Instructions
Step 1 – Bake the Potatoes (Ahead of Time):
Scrub and pierce your russet potatoes, then bake at 400°F (200°C) until fork-tender (about 1 hour). Cool completely, then refrigerate overnight. Cold potatoes are easier to grate and give a better texture.
Step 2 – Prep the Mixture:
Peel the cold potatoes and coarsely grate them using a box grater. In a large bowl, gently mix the grated potatoes with sour cream, finely chopped shallots, shredded cheddar cheese, melted butter, salt, and pepper.
Step 3 – Assemble the Casserole:
Transfer the mixture into a buttered baking dish. Sprinkle a little extra cheese on top for a golden finish.
Step 4 – Bake:
Bake at 350°F (175°C) for about 30–35 minutes, or until bubbly and golden on top.
Step 5 – Serve Hot:
Let it rest for 5 minutes, then dig in!

Additional Tips
- Use cold, baked potatoes: This helps maintain texture and avoids a mushy casserole.

- Cheese options: Sharp white cheddar, Gruyère, or even Swiss cheese all work great here.
FAQ’s
1. Can I use red or Yukon Gold potatoes instead?
You can, but russet potatoes work best because they’re starchy and bake up fluffy.
2. Can I freeze Potatoes Romanoff?
Yes. Assemble the dish, wrap it tightly, and freeze before baking. Bake directly from frozen, adding extra time.
3. What’s the difference between Potatoes Romanoff and scalloped potatoes?
Scalloped potatoes are made with sliced potatoes in a creamy sauce. Potatoes Romanoff uses grated baked potatoes for a more textured, fluffy result.
4. Can I use Greek yogurt instead of sour cream?
Yes! It will add a slightly tangier flavor but still deliver a creamy texture.
5. Can I reheat leftovers?
Absolutely. Reheat in the oven or microwave until warmed through. The oven keeps it crispier.
6. How do I avoid it getting watery?
Use cold, baked potatoes and avoid over-mixing. That keeps everything light and fluffy.
